Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Answer:
22.) 2.0651
23.) 4.231
Step-by-step explanation:
22.) Substitute values into equation
(x)(y) + 2 =
(2.1)(0.031) + 2 = 2.0651
23.) Substitute values into equation
(y) + (x)2
(0.031) + (2.1)2 = 4.231
156
Especially since the shape is convex
It would be 8.525
The 8 is 8
Divide 21 by 40
Multiply 14/20 by 5 to make the denominator 100. 14/20 x 5 = 70/100. So, 14/20 as a percentage is 70%.
